A process for the establishment and adjustment of a building board
2014
The invention relates to a method for setting up and adjustment of a building panel in a laser sintering or laser melting device 1, in which powder-like building material 3 coated on a surface of a building board 4 or a previously solidified building material layer 25 and by exposure to radiation energy, in particular laser radiation selectively for producing a component 2 is solidified, the building panel is 4 placed on a vertically movable support 5 of the laser sintering or laser melting system before beginning the building process, the upward-facing surface of the building board 4 before or after the call on the support 5 with a camera device 21 identifiable optical pattern 20 which building board 4 is provided with the pattern 20 is coated with building materials 3 in the SLS or SLM apparatus 1 such that the surface of the building board 4 is covered by a homogeneous building material layer 25 being subsequently stepwise by successively lifting the carrier 5 layer by layer, the powder of the building material layer 25 is removed and during or after each drawing a layer, the remaining layers of construction material is detected 25 by the camera apparatus 21, by continuing the layer-wise peeling of powder layers until through a building material residual layer 26 the defined, on the upward-facing surface of the building board 4 applied pattern 20 can be recognized by the camera device 21, by starting the construction process by solidifying the building material residual layer 26 and / or a further thereon layers of construction material, after the camera device 21 recognized the translucent through the construction material residual layer 26 defined patterns 20 Has.
